Point prevalence of wounds in a sample of acute hospitals in Canada

The prevalence of skin lesions and associated factors in hospitalised adult patients with cancer

OBJECTIVE

To assess the prevalence of skin lesions and evaluate the clinical and sociodemographic factors associated with their presence in hospitalised patients.

METHOD

This descriptive, cross-sectional, correlational study was performed in inpatient units and intensive care units of a cancer hospital in São Paulo, Brazil, after approval by the Institutional Research Ethics Committee. Data from hospitalised adult patients with cancer were collected during physical examinations and from medical records. A Chi-squared test, univariate analysis, a logistic regression model with results expressed as odds ratio (OR) and 95% confidence intervals (CI), and Classification and Regression Tree (CART) analysis were used to evaluate the data.

RESULTS

Of 341 patients, 80 had skin lesions, equating to an overall prevalence of 23.5%. The skin lesions included pressure injuries (10%), incontinence-associated dermatitis (6.7%), skin tears (6.5%), malignant wounds (3.8%) and complicated surgical wounds (3.2%). The factors associated with skin lesions in cancer patients were the use of disposable nappies (OR: 4.436) and age (59.1±15.1 years), according to the CART analysis, and the wearing of nappies (OR: 4.466, p<0.001), presence of ecchymosis (OR: 2.532, p<0.001) and infection (OR: 6.449, p=0.040), according to multiple regression analysis.

CONCLUSION

This study contributed to knowledge about prevalence and associated factors of skin lesions in hospitalised patients with cancer, allowing the implementation of preventive measures.

Choosing the Optimal Wound Dressing for Bathing After Total Knee Arthroplasty

BACKGROUND

Many surgical dressings claim to be waterproof and safe for bathing postoperatively. The purpose of this study is to evaluate and compare the effectiveness of commonly used dressings' ability to prevent water penetration while bathing. Additionally, a survey was used to determine satisfaction and cost analysis performed.

METHODS

Four different dressings were applied to 17 subjects' knees: Aquacel, Opsite, Acticoat, and Tegaderm. A folded Medline Gauze Sponge was weighed and placed under each dressing before and after showering and bathing (submergence under water) in order to measure water penetration (change in weight of sponge in grams). A failure was defined as any dressing that allowed a sponge weight change greater than 1 standard deviation, or 3.9 g. All participants were additionally asked to complete a short survey after testing about the dressings.

RESULTS

Tegaderm was found to have significantly less water penetration than all other dressings except Aquacel and demonstrated no failures with showering, significantly less than all other dressings. Tegaderm was also found to have significantly less water penetration than all other dressings except Acticoat with bathing and had significantly less failures than all other dressings. Furthermore, Tegaderm was found to be the most comfortable and lowest cost per dressing.

CONCLUSION

Tegaderm was overall the most effective at preventing water penetration, most comfortable, and most cost-effective. Aquacel was found to be equally as effective at preventing water penetration while showering but overall had more water penetration, had more failures, caused more discomfort, and was more expensive.

Determine what to measure and how to measure in clinical trials for the treatment of pressure injury: A protocol for the development of a core outcome set

BACKGROUND

A core outcome set (COS) is an agreed minimum set of outcomes that should be reported in all clinical trials in specific areas of health care. A considerable amount of trials did not report essential outcomes or outcomes measurement methods, which makes it challenging to evaluate the efficacy and safety of treatment strategies for pressure injury (PI) and produced significant heterogeneity of reported outcomes. It is necessary to develop a COS, which can be used for clinical trials in PI treatment.

METHODS/DESIGN

The development of this COS will be guided by an advisory group composed of clinicians, senior nurses, patients, and methodologists. We will search six databases and 2 registry platforms to identify currently reported PI treatment outcomes and outcome measurement instruments in randomized controlled trials, meta-analysis, and systematic reviews. We will also conduct a semi-structured interview with clinicians, nurses, and adult PI patients to collect their opinions on important outcomes. Each outcome of the initial list generated from systematic review and interviews will be scored and reach a consensus through two rounds of international Delphi survey with all key stakeholders. A face-to-face consensus meeting with key stakeholders will be conducted to finish a final COS and recommend measurement instruments for each outcome.

RESULTS

We will develop a COS that should be reported in future clinical trials to evaluate the effectiveness of PI treatment.

DISCUSSION

The COS will follow current guidance to develop a high-quality COS in the field of PI treatment to reduce heterogeneity in trial reporting, facilitate valid comparisons of new therapies, and improve the quality of clinical trials.

Barriers and facilitators for caregiver involvement in the home care of people with pressure injuries: A qualitative study

Aim

To explore the barriers and facilitators perceived by home caregivers regarding their involvement in the home care of people with pressure injuries.

Background

Although home caregivers are key in the process of caring for people with pressure injuries, little is known about their perceptions regarding their involvement in the same.

Methods

A qualitative study based on grounded theory involving a theoretical sample of 15 home caregivers of people with pressure injuries within the health district of Puertollano, Spain.

Results

This study identified three barriers (feminization of care, necessary life adaptations as a home caregiver, and the organization of health services) and three facilitators (the perceived family duty for caring, willingness to provide care, and satisfaction with the care received on behalf of primary care services) associated with caregiver involvement in the home care of pressure injuries.

Conclusions

The care of a person with pressure injuries is perceived as a duty and requires important adaptations affecting the home caregiver’s personal, social and work life. The emotional closeness and trust that develops between a patient and the primary care staff equals an involvement which, in turn, also has positive results for both the home caregiver and the patient.

Cost-of-illness studies in chronic ulcers: a systematic review

OBJECTIVE

To systematically review the published academic literature on the cost of chronic ulcers.

METHODS

A literature search was conducted in MEDLINE, EMBASE, HealthSTAR, Econlit and CINAHL up to 12 May 2016 to identify potential studies for review. Cost search terms were based on validated algorithms. Clinical search terms were based on recent Cochrane reviews of interventions for chronic ulcers. Titles and abstracts were screened by two reviewers to determine eligibility for full text review. Study characteristics were summarised. The quality of reporting was evaluated using a modified cost-of-illness checklist. Mean costs were adjusted and inflated to 2015 $US and presented for different durations and perspectives.

RESULTS

Of 2267 studies identified, 36 were eligible and included in the systematic review. Most studies presented results from the health-care public payer or hospital perspective. Many studies included hospital costs in the analysis and only reported total costs without presenting condition-specific attributable costs. The mean cost of chronic ulcers ranged from $1000 per year for patient out of pocket costs to $30,000 per episode from the health-care public payer perspective. Mean one year cost from a health-care public payer perspective was $44,200 for diabetic foot ulcer (DFU), $15,400 for pressure ulcer (PU) and $11,000 for leg ulcer (LU).

CONCLUSIONS

There was large variability in study methods, perspectives, cost components and jurisdictions, making interpretation of costs difficult. Nevertheless, it appears that the cost for the treatment of chronic ulcers is substantial and greater attention needs to be made for preventive measures.

Conceptualisations on home care for pressure ulcers in Spain: perspectives of patients and their caregivers

BACKGROUND

Pressure ulcers represent an important worldwide public health problem, which substantially decrease the quality of life of those affected. Yet, few studies to date have analysed the perceptions regarding home care for pressure ulcers.

AIMS

To explore the conceptualisations regarding home care of pressure ulcers from the perspective of affected patients and their caregivers.

METHODS

A qualitative study design based on Grounded Theory. In-depth interviews were conducted on a theoretical sample of 10 people currently suffering from a pressure ulcer, or who had experienced one in the past, and 15 caregivers of patients who had suffered from this pathology, all of whom came from the four health districts of Puertollano (Ciudad Real, Spain).

FINDINGS

Two categories emerged to explain the conceptualisations regarding pressure ulcers: (a) Cause of the pressure ulcer with three subcategories (unavoidable injuries, caregiver's lack of knowledge and painful wounds) and (b) Preferences regarding caring for pressure ulcers with two subcategories (home care as the best approach to treatment and noninstitutionalisation).

CONCLUSIONS

This research provides a novel perspective on the specific problems surrounding home care for pressure ulcers, including the perceptions of both patients and their caregivers. It is important to give a voice to patients and their caregivers as this will help understand their needs and improve the care provided. Further studies are required to improve current treatment protocols and clinical practice guidelines for the prevention and treatment of this pathology.

Management of Patients With Venous Leg Ulcers: Challenges and Current Best Practice

Introduction It is well documented that the prevalence of venous leg ulcers (VLUs) is increasing, coinciding with an ageing population. Accurate global prevalence of VLUs is difficult to estimate due to the range of methodologies used in studies and accuracy of reporting. (1) Venous ulceration is the most common type of leg ulceration and a significant clinical problem, affecting approximately 1% of the population and 3% of people over 80 years of age (2) in westernised countries. Moreover, the global prevalence of VLUs is predicted to escalate dramatically, as people are living longer, often with multiple comorbidities. Recent figures on the prevalence of VLUs are based on a small number of studies, conducted in Western countries, and the evidence is weak. However, it is estimated that 93% of VLUs will heal in 12 months, and 7% remain unhealed after five years. (3) Furthermore, the recurrence rate within 3 months after wound closure is as high as 70%. (4) (-6) Thus, cost-effective adjunct evidence-based treatment strategies and services are needed to help prevent these ulcers, facilitate healing when they occur and prevent recurrence. The impact of a VLU represents social, personal, financial and psychological costs on the individual and further economic drain on the health-care system. This brings the challenge of providing a standardised leg ulcer service which delivers evidence-based treatment for the patient and their ulcer. It is recognised there are variations in practice and barriers preventing the implementation of best practice. There are patients not receiving appropriate and timely treatment in the initial development of VLUs, effective management of their VLU and preventing recurrence once the VLU has healed. Health-care professionals (HCPs) and organisations must have confidence in the development process of clinical practice guidelines and have ownership of these guidelines to ensure those of the highest quality guide their practice. These systematic judgments can assist in policy development, and decision making, improve communication, reduce errors and improve patient outcomes. There is an abundance of studies and guidelines that are available and regularly updated, however, there is still variation in the quality of the services offered to patients with a VLU. There are also variations in the evidence and some recommendations contradict each other, which can cause confusion and be a barrier to implementation. (7) The difference in health-care organisational structures, management support and the responsibility of VLU management can vary in different countries, often causing confusion and a barrier to seeking treatment. These factors further complicate the guideline implementation process, which is generally known to be a challenge with many diseases. (8).

Combined Topical Growth Factor and Protease Inhibitor in Chronic Wound Healing: Protocol for a Randomized Controlled Proof-of-Concept Study

Background

Leg ulcers due to venous disease are chronic wounds that can take 6 or more months to heal. Growth factors have been used to try and improve this healing; however, many such studies have failed, and that is thought to be due to enzymes in the wound that degrade the growth factors and prevent them from working.

Objective

This is a proof-of-concept study that will evaluate the treatment of chronic leg ulcers with topically applied growth factors that are combined with a therapy to prevent their inactivation in the wound. This combined therapy has the potential to speed up the healing of these wounds and thereby improve the quality of life of patients and reduce the costs to the health system.

Methods

This will be a double-blind, placebo-controlled, randomized controlled proof-of-concept study comparing growth factor with protease inhibitor wound dressings to growth factors with standard wound dressings.

Results

The project was funded by the Canadian Institutes for Health Research and enrollment is expected to be initiated in 2018. It is expected that results will be available in 2021.

Conclusions

It is expected that the results of this trial will inform as to whether modifying the wound environment through the use of protease inhibitors increases the effectiveness of topically applied growth factors in the healing of chronic wounds.

Prevalence of foot disease and risk factors in general inpatient populations: a systematic review and meta-analysis

OBJECTIVE

To systematically review studies reporting the prevalence in general adult inpatient populations of foot disease disorders (foot wounds, foot infections, collective 'foot disease') and risk factors (peripheral arterial disease (PAD), peripheral neuropathy (PN), foot deformity).

METHODS

A systematic review of studies published between 1980 and 2013 was undertaken using electronic databases (MEDLINE, EMBASE and CINAHL). Keywords and synonyms relating to prevalence, inpatients, foot disease disorders and risk factors were used. Studies reporting foot disease or risk factor prevalence data in general inpatient populations were included. Included study's reference lists and citations were searched and experts consulted to identify additional relevant studies. 2 authors, blinded to each other, assessed the methodological quality of included studies. Applicable data were extracted by 1 author and checked by a second author. Prevalence proportions and SEs were calculated for all included studies. Pooled prevalence estimates were calculated using random-effects models where 3 eligible studies were available.

RESULTS

Of the 4972 studies initially identified, 78 studies reporting 84 different cohorts (total 60 231 517 participants) were included. Foot disease prevalence included: foot wounds 0.01-13.5% (70 cohorts), foot infections 0.05-6.4% (7 cohorts), collective foot disease 0.2-11.9% (12 cohorts). Risk factor prevalence included: PAD 0.01-36.0% (10 cohorts), PN 0.003-2.8% (6 cohorts), foot deformity was not reported. Pooled prevalence estimates were only able to be calculated for pressure ulcer-related foot wounds 4.6% (95% CI 3.7% to 5.4%)), diabetes-related foot wounds 2.4% (1.5% to 3.4%), diabetes-related foot infections 3.4% (0.2% to 6.5%), diabetes-related foot disease 4.7% (0.3% to 9.2%). Heterogeneity was high in all pooled estimates (I(2)=94.2-97.8%, p<0.001).

CONCLUSIONS

This review found high heterogeneity, yet suggests foot disease was present in 1 in every 20 inpatients and a major risk factor in 1 in 3 inpatients. These findings are likely an underestimate and more robust studies are required to provide more precise estimates.

Open-label clinical trial comparing the clinical and economic effectiveness of using a polyurethane film surgical dressing with gauze surgical dressings in the care of post-operative surgical wounds

Surgical site infection (SSI) is a common postoperative complication and can cause avoidable morbidity and excessive costs for the health service. Novel dressings, designed specifically for postoperative wounds, can help to reduce the risk of SSI and other complications such as blistering. This study compared the use of a new polyurethane film surgical dressing (Opsite Post-Op Visible, Smith & Nephew, Hull, UK) with gauze and tape in the management of postoperative wounds. The results show that the polyurethane film dressing results in a significant reduction in SSI (1·4% versus 6·6%, P = 0·006) as well as a reduction in other postoperative wound complications (e.g. blistering and erythema). Economic analysis conducted alongside the study suggests that these improved outcomes can be achieved at a lower treatment cost than gauze and tape dressings. The modest incremental cost of the polyurethane film surgical dressing is easily offset by the reduction in the costs related to treating SSI and other wound complications associated with gauze and tape dressings.

Nursing students' knowledge and attitude on pressure ulcer prevention evidence-based guidelines: a multicenter cross-sectional study

BACKGROUND

Pressure ulcers still remain a significant problem in many healthcare settings. Poor knowledge and negative attitudes toward pressure ulcer prevention could undesirably affect preventive care strategies.

OBJECTIVE

To assess both knowledge and attitudes among nursing students on Pressure Ulcer Prevention Evidence-Based Guidelines.

DESIGN

A multicenter cross-sectional survey was carried out from December 2012 to August 2013.

SETTINGS

The study was carried out in seven Italian nursing schools.

PARTICIPANTS

We involved a convenience sample of nursing students (n=742) METHODS: Data were collected using two validated questionnaires to assess students' knowledge and attitudes on pressure ulcer prevention.

RESULTS

The overall Knowledge and Attitude scores were 51.1% (13.3/26) and 76.7% (39.9/52), respectively. We found a weak correlation between total Knowledge scores and total Attitude scores (rho=0.13, p<0.001). We also observed that nursing students' year of education, training experience and number of department frequented during their clinical placement were significantly related to both the Knowledge and the Attitude total scores (p<0.05).

CONCLUSIONS

Nursing students' knowledge on pressure ulcer prevention was relatively low. However, we observed an association between a high level of education/training experience and higher knowledge scores. Most of the participants showed high attitude scores. These results suggest that positive attitudes toward pressure ulcer prevention may contribute to the compliance with the guidelines in clinical practice.

Reduction in wound healing times, cost of consumables and number of visits treated through the implementation of an electronic wound care system in rural Australia

Globally, wound care costs the health care system 2-3% of the total expenditure on health, which equates to several billion dollars annually. To date, there are little data on the cost and healing rates of various wounds. This has been partly because of the difficulty in tracking wound management as the majority of wound care data has been focused on retrospective data from hospitals, general practice clinics and aged care facilities. This study reports on wound healing and cost of wounds collected from a larger project using the mobile wound care (MWC) electronic documentation system, which has been described elsewhere. The study involved 2350 clients from four health service districts in the Gippsland region in rural Australia who received treatments as part of the MWC research project (2010-2012), with a total of 3726 wounds identified (so an average of 1·6 wounds per client). By the end of the data collection period, 81% of these wounds had healed. A significant drop in healing time, cost of consumables and number of visits was found across the 3-year period.

Relationships within inpatient physician housestaff teams and their association with hospitalized patient outcomes

IMPORTANCE

Improving inpatient care delivery has historically focused on improving individual components of the system. Applying the complexity science framework to clinical systems highlights the important role of relationships among providers in influencing system function and clinical outcomes.

OBJECTIVE

To understand whether inpatient medical physician teams can be differentiated based on the relationships among team members, and whether these relationships are associated with patient outcomes, including length of stay (LOS), unnecessary length of stay (ULOS), and complication rates.

DESIGN

Eleven inpatient medicine teams were observed daily during attending rounds for 2- to 4-week periods from September 2008 through June 2011. Detailed field notes were taken regarding patient care activities, team behaviors, and patient characteristics and outcomes. Behaviors were categorized using the Lanham relationship framework, giving each team a relationship score. We used factor analysis to assess the pattern of relationship characteristics and assessed the association between relationship characteristics and patient outcomes.

SETTING

Observations occurred at the Audie L. Murphy Veterans Affairs Hospital and University Hospital in San Antonio, Texas.

PARTICIPANTS

Physicians were chosen based on rotation schedules, experience, and time of year. Patients were included based on their admission to the inpatient medicine teams that were being observed.

MAIN MEASURES

Relationship scores were based on the presence or absence of 7 relationship characteristics. LOS, ULOS, and complication rates were assessed based on team discussions and chart review. The association between relationships and outcomes was assessed using the Kruskal-Wallis rank sum test.

RESULTS

We observed 11 teams over 352.9 hours, observing 1941 discussions of 576 individual patients. Teams exhibited a range of 0 to 7 relationship characteristics. Relationship scores were significantly associated with complication rates, and presence of trust and mindfulness among teams was significantly associated with ULOS and complication rates.

CONCLUSIONS

Our findings are an important step in understanding the impact of relationships on the outcomes of hospitalized medical patients. This understanding could expand the scope of interventions to improve hospital care to include not only process improvement but also relationships among providers.

Improving outcomes of hospitalized patients: the Physician Relationships, Improvising, and Sensemaking intervention protocol

BACKGROUND

Our goal is to improve the safety and effectiveness of inpatient care. Rather than focus on improving process of care, we focus on the social structure within physician teams. We have developed the Physician Relationships, Improvising, and Sensemaking (PRISm) intervention to improve the way physician teams round, enabling them to better relate, make sense of their patients' conditions, and improvise in uncertain clinical situations. We are currently studying the impact of PRISm on adverse events and complications in hospitalized patients. This manuscript describes the PRISm intervention.

METHODS/DESIGN

PRISm is a structured communication tool consisting of three components: daily briefings before rounds; use of the Situation, Task, Intent, Concern, and Calibrate (STICC) framework during rounds as part of the discussion of individual patients; and debriefings after rounds. We are implementing the PRISm intervention on eight inpatient medical and surgical physician teams in the South Texas Veterans Health Care System. We are assessing PRISm impact on the way team members relate to each other, round, and discuss patients through pre- and post-implementation observations and surveys. We are also assessing PRISm impact on complications and adverse events. Finally, we are interviewing physicians regarding their experience using the intervention.

DISCUSSION

Our results will allow us to begin to understand the potential impact of interventions designed to improve how providers relate to each other, improvise, and make sense of what is happening as a strategy for improving inpatient care. Our in-depth data collection will enable us to assess how relationships, improvising, and sensemaking influence patient outcomes, potentially through creating shared mental models or enhancing distributed cognition during clinical reasoning. Finally, our results will lay the groundwork for larger implementation studies to improve clinical outcomes through improving how providers, and providers, patients, and caregivers, relate.

The lived experience of the wound care nurse in caring for patients with pressure ulcers

The aim of the study was to report the lived experience of the wound care nurse (WCN) in caring for patients with pressure ulcers (PU). WCN play an important role in caring for patients with PU, but the effect on caring for individuals with such wounds is poorly understood. A descriptive and interpretative study on the life worlds of spatiality, temporality, relationality and corporeality was carried out. Utilising the hermeneutic Heideggerian phenomenology, data were collected over a 3-month period in 2012 using in-depth interviews with five WCN. The interviews revealed eight themes: 'challenge', 'making sense of it all', 'coping and self-care', 'advocate of mine/making a difference', 'knowledge and technology', 'we have seen what can happen', 'holistic caring' and 'frustration'. Twenty-five sub-themes were also identified. WCN experienced a demanding and rewarding role of caring, influenced by the environment and the challenges with individuals living with PU. This study demonstrated an enriching yet challenging role. Recommendations for WCN, health care authorities and education providers include raising awareness of the importance of self-care, greater recognition of the effect of this role on patients with PU and changing education to include reflective practice and resilience strategies.

The occurrence of adverse events potentially attributable to nursing care in medical units: cross sectional record review

BACKGROUND

Ensuring the safety of hospitalized patients remains a major challenge for healthcare systems, and nursing services are at the center of hospital care. Yet our knowledge about safety of nursing care is quite limited. In fact, most earlier studies examined one, or at most two, indicators, thus presenting an incomplete picture of safety at an institutional or broader level. Furthermore, methodologies have differed from one study to another, making benchmarking difficult.

OBJECTIVES

The aim of this study was to describe the frequencies of six adverse events widely considered in the literature to be nursing-sensitive outcomes and to estimate the degree to which these events could be attributed to nursing care.

METHOD

Cross-sectional review of charts of 2699 patients hospitalized on 22 medical units in 11 hospitals in Quebec, Canada. The events included: pressure sores, falls, medication administration errors, pneumonias, urinary infections, and inappropriate use of restraints. Experienced nurse reviewers abstracted patients' charts based on a grid developed for the study.

RESULTS

Patient-level risk for at least one of these six adverse events was 15.3%, ranging from 9% to 28% across units. Of the 412 patients who experienced an event, 30% experienced two or more, for a total of 568 events. The risk of experiencing an adverse event with consequences was 6.2%, with a unit-level range from 3.2% to 13.5%. Abstractors concluded that 76.8% of the events were attributable to nursing care.

CONCLUSION

While the measurement approach adopted here has limitations stemming from reliance on review of documentation, it provided a practical means of assessing several nursing-sensitive adverse events simultaneously. Given that patient safety issues are so complex, tracking their prevalence and impact is important, as is finding means of evaluating progress in reducing them.

Trypsin potentiates human fibrocyte differentiation

Trypsin-containing topical treatments can be used to speed wound healing, although the mechanism of action is unknown. To help form granulation tissue and heal wounds, monocytes leave the circulation, enter the wound tissue, and differentiate into fibroblast-like cells called fibrocytes. We find that 20 to 200 ng/ml trypsin (concentrations similar to those used in wound dressings) potentiates the differentiation of human monocytes to fibrocytes in cell culture. Adding trypsin inhibitors increases the amount of trypsin needed to potentiate fibrocyte differentiation, suggesting that the potentiating effect is dependent on trypsin proteolytic activity. Proteases with other site specificities such as pepsin, endoprotease GluC, and chymotrypsin do not potentiate fibrocyte differentiation. This potentiation requires the presence of albumin in the culture medium, and tryptic fragments of human or bovine albumin also potentiate fibrocyte differentiation. These results suggest that topical trypsin speeds wound healing by generating tryptic fragments of albumin, which in turn potentiate fibrocyte differentiation.

Identifying wound prevalence using the Mobile Wound Care program

Measuring the prevalence of wounds within health care systems is a challenging and complex undertaking. This is often compounded by the clinicians' training, the availability of the required data to collect, incomplete documentation and lack of reporting of this type of data across the various health care settings. To date, there is little published data on wound prevalence across regions or states. This study aims to identify the number and types of wounds treated in the Gippsland area using the Mobile Wound Care (MWC™) program. The MWC program has enabled clinicians in Gippsland to collect data on wounds managed by district nurses from four health services. The main outcomes measured were patient characteristics, wound characteristics and treatment characteristics of wounds in Gippsland. These data create several clinical and research opportunities. The identification of predominant wound aetiologies in Gippsland provides a basis on which to determine a regional wound prospective and the impact of the regional epidemiology. Training that incorporates best practice guidelines can be tailored to the most prevalent wound types. Clinical pathways that encompass the Australian and New Zealand clinical practice guidelines for the management of venous leg ulcers can be introduced and the clinical and economical outcomes can be quantitatively measured. The MWC allows healing times (days) to be benchmarked both regionally and against established literature, for example, venous leg ulcers.

Pressure ulcers: development and psychometric evaluation of the attitude towards pressure ulcer prevention instrument (APuP)

BACKGROUND

Pressure ulcers continue to be a significant problem in hospitals, nursing homes and community care settings. Pressure ulcer incidence is widely accepted as an indicator for the quality of care. Negative attitudes towards pressure ulcer prevention may result in suboptimal preventive care. A reliable and valid instrument to assess attitudes towards pressure ulcer prevention is lacking.

AIMS AND OBJECTIVES

Development and psychometric evaluation of the Attitude towards Pressure ulcer Prevention instrument (APuP).

DESIGN

Prospective psychometric instrument validation study.

METHODS

A literature review was performed to design the instrument. Content validity was evaluated by nine European pressure ulcer experts and five experts in psychometric instrument validation in a double Delphi procedure. A convenience sample of 258 nurses and 291 nursing students from Belgium and The Netherlands participated in order to evaluate construct validity and stability reliability of the instrument. The data were collected between February and May 2008.

RESULTS

A factor analysis indicated the construct of a 13 item instrument in a five factor solution: (1) attitude towards personal competency to prevent pressure ulcers (three items); (2) attitude towards the priority of pressure ulcer prevention (three items); (3) attitude towards the impact of pressure ulcers (three items); (4) attitude towards personal responsibility in pressure ulcer prevention (two items); and (5) attitude towards confidence in the effectiveness of prevention (two items). This five factor solution accounted for 61.4% of the variance in responses related to attitudes towards pressure ulcer prevention. All items demonstrated factor loadings over 0.60. The instrument produced similar results during stability testing [ICC=0.88 (95% CI=0.84-0.91, P<0.001)]. For the total instrument, the internal consistency (Cronbachs alpha) was 0.79.

CONCLUSION

The APuP is a psychometrically sound instrument that can be used to effectively assess attitudes towards pressure ulcer prevention in patient care, education, and research. In further research, the association between attitude, knowledge and clinical performance should be explored.
